Abstract

Background: Acral actinic keratosis (AK) lesions are considered difficult to treat, and published data for photodynamic therapy (PDT) on these lesions is limited. Thus, we evaluated sustained efficacy, safety, and satisfaction after PDT for AK on the hands. Methods: We analysed subgroup data for treatment on the hands from a randomised, double-blind, intra-individual phase III study. All participants previously underwent up to two field-directed red light PDTs with 10 % 5-aminolevulinic acid nanoemulsion gel (BF-200 ALA). Assessments included pain during PDT, clearance and recurrence rates, and satisfaction. Results: 24 participants treated on the hands were included; 21 participants were analysed. Complete clearance rates with BF-200 ALA were 90.9 % (lesion-based) and 76.2 % (per participant's side), both markedly higher than with vehicle. The lesion recurrence rate with BF-200 ALA was 29.0 %. Adverse events reflected the mode of action. Mean pain intensities were 4.8 ± 3.8 (BF-200 ALA) and 0.8 ± 2.1 (vehicle) on an 11-point numeric rating scale. Most participants (81.0 %) rated their satisfaction with BF-200 ALA as very good or good. Conclusion: This subgroup analysis indicates that PDT with BF-200 ALA provides a suitable treatment for AK lesions on the hands.
